Abstract

PURPOSE: To evaluate the advantages of transarticular reconstruction and fixation of metaphysis by MIPO technique for AO type C2-C3 fractures of the distal femur. MATERIAL AND METHODS: In a retrospective study conducted from January 1996 to December 1997, AO type C2-C3 fractures of the distal femur were treated using three techniques; 1) A group-MIPO technique and medial parapatellar arthrotomy for the direct reduction of the condylar block(10 cases), 2) B group-conventional AO technique(8 cases) 3) C group-closed supracondylar nailing(4 cases). Minimal followup time was 12 months.
RESULTS
Time to bone healing was 15 weeks in A group, 20 weeks in B group, and 16 weeks in C group. complication rate was 0% in A group, 50% in B group, and 50% in C group. normal alignment between 0 & valgus 9 degrees was 100% in A group, 75% in B group, and 50% in C group. Neer score was 90% excellent or satisfactory in A group, 75% in B group, and 50% in C group respectively. The results of A group was better than those of B and C group.
CONCLUSION
Transarticular joint reconstruction and MIPO technique for AO type C2-C3 fractures of the distal femur is an excellent technique to obtain more rapid bony union with less complications.
